National Geographic : 1899 Nov
GEOGRAPHIC MISCELLANEA which was held at Dover the second week of September. " Oceanog raphy," the title of Sir John Murray's presidential address to the Geo graphical Section, is published in full and is accompanied by a bathy metrical chart of the ocean showing the " deeps" according to Sir John Murray. From these results it appears that considerably more than half of the sea-floor lies at a depth exceeding 2,000 fathoms. He empha 'sizes the fact that the recent soundings of the German steamship Val diria in the Atlantic, Indian, and Southern oceans, as well as the many thousands of deep soundings taken within the last decade, have in but few instances caused any very great alteration in the positions of the con tour lines on the Challenger maps. THE delegates of the National Geographic Society to the International Geographical Congress in Berlin, on their return to the United States, report the meeting a success in every way. Gen. A. W . Greely, U. S. A., and Mr H. G. Bryant, president of the Philadelphia Geographical Society, were elected honorary vice-presidents of the Congress. The next place of meeting was referred to the executive committee for decision. Gen. Greely presented a number of papers, among which the following may be mentioned: " Geographical Work of the American Commission on the Venezuelan Boundary," by Marcus Baker; "Late Researches by the U. S. Weather Bureau," by H. C . Frankenfield; "Geographical Work of the U. S. Coast and Geodetic Survey," by J. M. Hayward ; " Geograph ical Work of the U. S . Department of Agriculture," by John Hyde; "United States Geological Surveys and Geographical Work," by C. D. Walcott; " Geographical Researches of the U. S . Bureau of Ethnology," by W J McGee. Ambassador Andrew D. White, Major H. T . Allen, U.S . A., Prof. Wm. M. Davis, Miss E. R . Scidmore, Dr L. A . Bauer, and Mr Marcus Baker also represented the National Geographic Society. An account of the proceedings of the Congress will appear in a later num ber of the Magazine. A RECENT number of Nature contains the following interesting statement: " From the reports in the AgriculturalJournal,published by the Cape De partment of Agriculture, it appears that much success in exterminating locusts by inoculation with the locust disease fungus has been attained in many districts. The fungus is prepared and supplied by the director of the Bacteriological Institute, Graham's Town, at a cost of six pence per tube to all applicants residing in Cape Colony. One of the reports upon its use states that over a hundred locusts which were inoculated with the fungus disease were distributed among a swarm, and on the next morn ing and the following days large numbers of dead ones were in the sand dunes, being killed by the fungus, as microscopical examination and fur ther experiments with the bodies proved. The growth of fungus from the dead locusts produced a fungus more rapid in growth, but smaller in size, than the government fungus. In another case the fungus was mixed in luke-warm water, and young locusts were released after immersion in the liquid. After three days' rainfall and on the afternoon of the fourth day locusts were found in heaps in the bushes about three miles from where they were immersed. Districts in which no such measures are being taken are much more infested with locusts than those where the fungus treatment is adopted."
